如何在 mustache.js 中迭代哈希 [英] How to Iterate over a hash in mustache.js

问题描述

给定这个哈希

a = {foo : { ... },酒吧 : { ... }，电击:{ ... }}

我想迭代它，但由于键不同，我不确定如何在 Mustache.js

输出看起来像这样 foo :(这里的内容)

解决方案

如果您知道要检索的嵌套对象中的键，则可以使用函数.

参见:http://jsfiddle.net/jimschubert/zPWDJ/

js:

$(function() {变量名称 = {一种": [{"foo": { "name": "foo name"}},{"bar": { "name": "bar name"}},{"zap": { "name": "zap name"}}],n":函数(){var self = this;var n = "";Object.keys(self).forEach(function(k, v) {if (typeof self[k] == "object") {if(!n) n = self[k]["name"];}});返回 n;}};var template = $('#template').html();var out = $('#output');var html = Mustache.to_html(模板，名称)；控制台日志(html)；out.html(html);});

html:

<h1>输出</h1><div id="输出">

这当然假设你的数据是一个对象数组(你帖子中的 a 可能是更大数组的一个键，也许?)如果你没有数组，我不不明白为什么你不能为一个对象调整它，并为你正在寻找的每个键的任何属性创建一个 getter 函数.

Given this hash

a = {
  foo : { ... },
  bar : { ... },
  zap : { ... }
}

i want to iterate over it but since the keys are different I am not sure how to in Mustache.js

the output will look something like this foo : (contents here)

解决方案

If you know the key in the nested object that you're trying to retrieve, you can use a function.

see: http://jsfiddle.net/jimschubert/zPWDJ/

js:

$(function() {
    var names = {
        "a": [
            {"foo": { "name": "foo name"}},
            {"bar": { "name": "bar name"}},
            {"zap": { "name": "zap name"}}
        ],
        "n": function() {
            var self = this;
            var n = "";
            Object.keys(self).forEach(function(k, v) {
                if (typeof self[k] == "object") {
                    if(!n) n = self[k]["name"];
                }
            });
            return n;
        }
    };

    var template = $('#template').html();
    var out = $('#output');
    var html = Mustache.to_html(template, names);
    console.log(html);
    out.html(html);
});​

html:

<script id="template" class="template" type="text/x-mustache">
{{#a}}
<p>{{n}}</p>
{{/a}}
</script>

<h1>Output</h1>
<div id="output">
</div>
​

This of course assumes your data is an array of objects (the a in your post would be one key of a greater array, maybe?) If you don't have an array, I don't see why you wouldn't be able to adjust this for an object and make a getter function for whatever properties of each key you're looking for.
